Procedure

A solution of 3-(4-benzoylamino-phenylmethyl)-1-methyl-1H-indole-5-carboxylic acid (64 mg, 0.16 mmol), DIPEA (0.14 mL, 0.8 mmol), HATU (68 mg, 0.18 mmol), hydroxylamine hydrochloride (56 mg, 0.8 mmol) and DMF (4 mL) was stirred for 19 hr at room temperature. The reaction mixture was then subjected to HPLC purification to provide 3-(4-benzoylamino-phenylmethyl)-1-methyl-1H-indole-5-carboxylic acid hydroxyamide (22 mg, 34% yield). 1H NMR (400 MHz, DMSO) δ 11.06 (s, 1H), 10.18 (s, 1H), 7.99 (s, 1H), 7.93 (d, 2H, J=7.2 Hz), 7.67 (d, 2H, J=8.7 Hz), 7.57 (m, 2H), 7.53 (d, 2H, J=7.7 Hz), 7.43 (d, 1H, J=8.2 Hz), 7.27 (d, 2H, J=8.2 Hz), 7.19 (s, 1H), 4.03 (s, 2H), 3.76 (s, 3H).
